To all whom it may concer-n.' V y A Be it known that I, THOMAS M. TA'GGART, a citizen of the United States, and a resident of Belvedere, Marin county, California,

have invented new and useful Improven ments in Gasifiers for LowGrravity Oils, of

which the following is a specification.

My invention has for its principal object means whereby low gravity oils may be readily ignited, as for use in burners. A further object of my invention is to provide an indestructible gasifier. These objects I accomplish by supporting a small quantity of the oil in a receptacle having very thin metal walls, and having an air exposed surface such that when a flame is appliedto the edge of the receptacle the heat is not withdrawn from the oil to any material degree and is available for gasifying the oil lm adjacent to the receptacle wall and the flame, to a suflicient degree to support combustion. The flame is then immediately transmitted over the balance of the receptacle exposed surface thus establishing ignition of the fuel oil.

`Where the fuel oil is to be gasified from a well at the bottom of the burner area I locate the gasifier at a point where it either receives the fuel direct from a fuel conveying tube, or, the gasifier may be partially immersed in the fuel in a well, such that ar portion of the fuel will run into the gasifier compartment, or the gasifier may be filledv with infusorial earth, or similar material, and the oil may be readily ignited from its surface in the manner described, or the gasifer may be raised within the burner to an exposed position so that it may be .readily reached by a flame from the top of the burner and thus ignited; or, pilot lights may be arranged adjacent to the gasifier in its depressed or any other convenient position.

By referring to the accompanying drawings my invention will be made clear.

Figure 1 is a plan view of a burner fitted with my gasifer.

Fig. 2 is a cross section of Fig. 1 on the section line II-II.

Fig. 3 is an enlarged section through a burner well and gasifierof Fig. 2.

Fig. 4 is an enlarged section through the well and gasifier and a portion of the burner similar to Fig. 1, but employing different means of mounting the gasifier and showing inert capillary material mounted therein serving as an absorbent.

Figf'is a, c-rossvsection partlydiagramf -matic showing another means of feedingthe fuel oil to the gasifier andals0gsl1owing pilot burners to ignite the fuel at the gasi- Throughout the figures similar numerals refer toy identical parts.

The numeral 1 indicates the well within which the fuel oil is gasifed, the said oil being fed through the supply connection 2 and rising in gasifier 3, which in the figures is shown of annular form. The gasifier 3 is supported within the well l, and preferably above any normal oil surface therein by rods as 4, 4 which may conveniently be adapted to pass through openings in the wall as 5. These latter may be supported from. the frame 6, preferably having a central rod 7, such that raising the central rod 7 as by the finger member 8 will raise the gasifier 3 to the top 9 of the burner 10e This gasier 3 is to be made of very thin metal, and I prefer to use a metal thickness of about #34 U. S. standard gage, or thinner, but good results may be obtained with` a thickness as great as #22, and in any event the metal thickness must be such that the heat conductivity of the body 0f the metal will not be such as to cause rapid heat abstraction from the igniting flame.

The fuel in the gasifier may then kbe readily ignited and the gasifier lowered into the position of Fig. 2, when it will ignite the gas in the burner 10 from the fuel which is now being gasified from the well 1. In the alternate construction, as indicated in Fig. 4, the gasifier 3 is filled with infusorial earth or other porous inert material, preferably molded therein, and which through capillary action absorbs the oil as from the well 1 and thus exposes an inflammable oil surface on the u per part as 11, which may now be ignite in the manner previously described.

cated inV Fig. 3 or Fig. 4, may be mounted either on the supporting wires 4 or on the cross bars 12, and by utilizing a pilot burner, or burners, as indicated at 15 in Fig. 5, will form the igniting means for the burner. After ignition, the flame from the fuel burns within the space 10, combustion being supported therein by air as through the holes 13, 14.

I claim: v

1. In a burner a gasifier for low gravity liquid fuel formed of thin metal and of annular formv and supported from below an annular chamber formed about a central axis and within which said gasfier is disposed and through which it may be raised, means extending through the bottom of said Chamber and supporting said gasfier and a` central member extending upward Substantially at the chamber axis and adaptedto operate said supportn means from above the burner to ralse an lower said gasier in said chamber.

2. In combination a gasifier'anda burner as Set forth lnlelann 1 where1n there are a plurality of members below the gasfier to hold it spaced from the'bottom of said chamber and wherein the bottom of said chamber is constructed and adapted to contain fuel adapted to be ignited byfsaid gasiier.

In testimony whereof, I have hereunto set my hand at San Francisco, California, `this 30 day of January, 1920.
